    Sales Associate Project


    for my Java course as a project we were to design a program that a sales associate would use to enter customer information, lookup prices and display the prices of items to the screen. well we were given a second project which builds upon this program. basiclly we were supposed to design a main menu for the sales associate and we were to put the main menu in a loop to where it repeated until the program was exited. my problem is I have a secondary menu for the sales associate to add items that a customer purchased, however I always get a run time error that the string index is out of bounds. I will post a copy of the code so you can get an idea.

    import java.util.Scanner;
    import java.io.*;

    * Created by Ryan Moore
    * This Program will present customer information for a sales associate

    public class Moore_PP2
    public static void main(String[] args) throws IOException

    final double taxRate = 0.08;

    double shoes;
    double tShirts;
    double shorts;
    double caps;
    double jackets;
    double prodAmt; // holds the cost without tax
    double cost; // holds the cost
    double tax; // holds the tax of the product
    double totalCost; // holds the total cost of the product
    String cust;
    String custName;
    String custName2;
    String custAdd; // holds the customers street address
    String custCity; // holds the customers city, state, and zip
    String custEmail; // holds the customers email
    String input; // holds the input from option 3
    char answer; // reads the first character from input on option 3
    int quantity; // holds the quantity of the product purchased
    int number; // holds the number entered on main screen
    int price; // holds the number entered for price lookup

    shoes = 50.00; // tells the price of shoes
    tShirts = 30.00; // tells the price of tshirts
    shorts = 75.00; // tells the price of shorts
    caps = 15.00; // tells the price of caps
    jackets = 100.00; // tells the price of jackets

    // sets the accumulator to 0
    totalCost = 0.0;

    // used to read input from the keyboard
    Scanner keyboard = new Scanner(System.in);

    // displays the main menu
    System.out.print("Welcome to the main menu. " + "Enter a number to continue.\n"
    + "Enter Customer information = 1\n" + "Price Lookup = 2\n"
    + "Display Total Bill = 3\n" + "Quit = 4\n");

    number = keyboard.nextInt();

    /* used to determine which number is entered
    * the switch statement was used from chapter 3 in section 3.9 page 154
    switch (number)
    case 1:
    // open the file for writing
    PrintWriter outputFile = new PrintWriter("Customer.txt");

    // asks for the customers name
    System.out.println("Enter Customers name");
    keyboard.nextLine(); //used to consume a remaining newline
    custName = keyboard.nextLine();

    // writes the name to the file

    // asks for the customers address
    System.out.println("Enter Customers Street Address");
    System.out.println("For example: 123 Fake Street");
    custAdd = keyboard.nextLine();

    // writes the customers address to the file

    // asks for the customers ciry, state, and zip
    System.out.println("Enter Customers City, State, and Zip Code.");
    System.out.println("For Example: Someplace, Tx. 77327");
    custCity = keyboard.nextLine();

    // writes the customers city, state, and zip to the file

    // asks for the customers email
    System.out.println("Enter Customers Email");
    custEmail = keyboard.nextLine();

    // writes the customers email address to the file

    // closes the file

    //used to print the input to the screen
    System.out.println("Customer: " + custName);

    System.out.println("City, State, and Zip: " + custCity);
    System.out.println("Email: " + custEmail);
    System.out.println("has been added to the database.");

    case 2:

    System.out.println("What Item would you like to look up?");
    System.out.println("Please enter a number to continue.\n");
    System.out.print("(1) Shoes.\n" + "(2) T-Shirts.\n" +
    "(3) Shorts.\n" + "(4) Caps.\n" + "(5) Jackets.\n");
    price = keyboard.nextInt();

    // switch statement for price look up menu
    switch (price)
    case 1:

    // displays the price for a pair of shoes
    System.out.println("The price for a pair of shoes"
    + " is: $" +shoes);

    case 2:

    // displays the price for a t-shirt
    System.out.println("The price for a T-Shirt is: $" +

    case 3:

    // displays the price for a pair of shorts
    System.out.println("The price for a pair of shorts " +

    System.out.println("Invalid Entry!");

    case 3:
    System.out.println("Enter Customers name");
    custName2 = keyboard.nextLine();

    System.out.println("What did the Customer purchase?");
    System.out.println("Type the word shoes, shirt, shorts, cap");
    System.out.println("or jacket");
    cust = keyboard.nextLine();

    if (cust.equalsIgnoreCase("shoes"))

    // asks the associate how many pairs the customer purchased
    System.out.println("How many pairs?");
    quantity = keyboard.nextInt();

    prodAmt = shoes * quantity;
    tax = prodAmt * taxRate;
    cost = prodAmt + tax;
    totalCost += cost;

    System.out.println("Did the customer purchase anything else?");
    System.out.println("Please Enter (1) for yes or (2) for no.");
    input = keyboard.nextLine();
    answer = input.charAt(0);

    } while (answer == 'y' || answer == 'Y');

    // opens the external file
    File file = new File("Customer.txt");
    Scanner inputFile = new Scanner(file);

    // reads the first line of the file
    String line = inputFile.nextLine();

    // reads the second line of the file
    String line2 = inputFile.nextLine();

    // reads the third line of the file
    String line3 = inputFile.nextLine();

    // reads the fourth line of the file
    String line4 = inputFile.nextLine();

    // diplays the output of the customer info to the screen
    // this part of the code isn't finished yet
    System.out.println("Product Purchased\t Quantity\t Total Cost");


    case 4:

    // exits the program

    System.out.println("Your input needs to be a 1, 2, 3, or 4.");

    /** the switch statements come from chapter 3 section 3.9
    * the println methods came from chapter 2 section 2.2
    * the scanner class was used from chapter 2 section 2.13
    * the various math calculations came from chapter 2

    the problem is with the if statement, I've tried with a switch statement and it has the same problem however if I omit the if statement the loop works just fine. any ideas on what my problem is?

    Please edit your post and wrap the code with code tags.

    get a run time error that the string index is out of bounds.
    Please post the full text of the error message that shows where the error happens and what the value of the index was.
